The retractable transport device comprises a carrying structure for a belt (30) composed of upper (4) and lower (11) beams which can move between the frames transverse to the movement direction of the cardboard. The upper beam can be lowered from a working position to a retracted position or raised by independent piston-cylinder absorbers. The device can be retracted between the two lateral transporters so as to allow the machine to be used in a new configuration without requiring any uncoupling of the transmission parts driving the belt.

Description

The middle conveyer of the collapsible displacement in folding-labelling machine

The middle conveyer that the purpose of this invention is to provide the collapsible displacement in a kind of folding-labelling machine; This machine generally is applied in the packaging industry, is used for making, for example by cutting the carboard that plate is formed.

This machine is made up of one group of assembly, the quantity of assembly only depends on that selected chamber type need carry out the complexity of operation when making, it includes usually at least: a continuous page or leaf machine, and it continues cutting material into from the stockpile singly uses for chamber production; A camber jack extrudes the first and the 3rd backfin in advance between 90 ° and 180 °, reopen cutting material then; A folding assembly that has dogging spare, its earlier sheet preceding alive of cutting material will be lived thereafter then sheet folding to 180 °; Paste station for one; A tucker is used for the second and the 4th backfin that folding goes out cutting material; A compactor, it is compressing the second and the 4th backfin, makes chamber be in stratiform; At last, a receiving unit, it receives chamber and makes it to keep pressured state so that make viscose glue stiff.Cutting material transporting by the belt conveyer from a station to another station carried out, and this conveyer clamps cutting material by the friction force between following belt and the last belt or by the friction force between following belt and the upper support roller.

And just in the tucker of the second and the 4th backfin of implementing the folding cutting material, the conveyer of collapsible displacement uses.This station generally includes the belt conveyer, and they are settled along the direction end wise of object running route; With a plurality of folding assemblies, for example folding belt, folding spiral, folding plate and folding ramp.All these assemblies preferably are installed on three transversely movable longerons of the size and dimension according to cutting material to be processed substantially linearly.In tucker, the operation of cutting material in manufacturing process mainly guaranteed by upper and lower intermediate belt conveyer and two pairs of upper and lower side belt conveyers.Folding is to carry out gradually along with the distortion geometric configuration of a side folding belt, twists in this at this folding belt and is guaranteed by a folding spiral.

When people wish on the same equipment when a kind of working size forwards another kind of different size to, can easily expect, as long as horizontal ground moves and supporting conveyer belt and folding assembly between the support of folding-labelling machine.Yet, if the maximum Effective width of this machine is to be determined by the distance of separating its two stands basically, determine by the summation of three belt widths then as for its minimum Effective width that so these three belts are the belt of side conveyer and the belt of middle conveyer.If people wish to use this same folding-labelling machine to process the cutting material of its size less than the determined minimum width of above-mentioned machine, conveyer is to reduce its position occupied in the middle of so just need getting rid of from folding-labelling machine.Conveyer in the middle of if related operation is to take off on that, this can not produce any special problem so, conveyer can easily be taken away from the manufacturing line top that is in dead position in the middle of last, yet situation is just different for that down middle conveyer, and it need entirely be dismantled.The drive belt of conveyer in the middle of this disassembling section program need get loose and take off is extracted transmission shaft out, entirely takes out the intermediate longitudinal girder that is supported on the machine rack then.The inconvenience of operation, some parts heavy and this centre portion that is not easy to get at folding-labelling machine, it is tediously long that everything takes operation task, makes us tired, do not solve this operation task and occur any other method as yet up to today.

The present invention is just in order to overcome these defectives, it proposes a kind of following middle conveyer of collapsible displacement, this device can easily be placed in the space that two side conveyers of installing are side by side reserved, and can not produce any obstruction between them when operation.Clearly, have only when the corresponding conveyer of going up, when itself was in the position of collapsible displacement above manufacturing line, following middle conveyer just shrank displacement.For folding-labelling machine when adopting the cutting material of large scale and middle size, owing to this contraction displacement and in extremely short setup time, can also smooth work just should expand its Effective width, up to approaching only two width that the belt of installing side by side is occupied of minimum size.

So, the middle conveyer that the purpose of this invention is to provide a kind of collapsible displacement, be a kind of at the wrapping plate-like articles of making, the middle conveyer of the collapsible displacement in the folding-labelling machine of carton or carboard for example, described folding-labelling machine includes two supports, two side conveyers between this two stands, have been settled especially, the part that transports wherein is respectively a belt, the conveyer of the collapsible displacement of the present invention is characterised in that it is made up of a kind of structure, this structure can be introduced belt, include four attaching partss that can between described folding-labelling machine support, move laterally with respect to described plate-like articles service direction, longeron on one is arranged in described attaching parts, should go up longeron owing to have the effect of damper element independently can be easily to make it carry out a motion under oblique to reduce with hand, be transformed into the position of collapsible displacement or rising once more on the contrary from a control position, feature of the present invention is that also it can be in this wise shrinks displacement between two side conveyers, be that this operation can make folding-labelling machine use in new configuration, and need not take the required Transmission of any independent drive belt apart, even this belt can also rotate running in the contraction displaced condition, feature of the present invention is that also it can settle described side conveyer in this wise side by side, and promptly described folding-labelling machine effectively transports width and can be reduced to minimum value.

Have that the present invention produces advantage be:

-because described device shrinks the semi-automation of displacement, and make its operation or the operation that do not move few and simple, so the setup time of machine greatly reduce;

-there are not heavy and the materials that hinder loading and unloading, thus the inconvenience of loading and unloading avoided, or conveyer in the middle of need just taking off by a kind of leverage;

-time of adjusting is short especially, thus the following belt that must carry out might avoid shrinking each time conveyer in the middle of the displacement time unclamps and again the tension operation or even change the work of belt down;

-removed the operation that the parts in folding-labelling machine support must be taken off from, for example take off the slide shaft of transmission shaft or longeron;

-consequently having reduced whole packing production cost, this production needs to adopt the contraction displacement mode to produce.

When giving a definition to the term of quoting in this specification sheets and describing the position of some parts in folding-labelling machine, people adopt " operator's side " (C.C) and " operator's opposite side (C.O.C) " term, and these terms are that the axis with machine is that benchmark comes appointment clearly.Adopt this term to avoid a left side commonly used and rightly causedly anyly obscure, because a left side or the right visual angle of depending on the viewer.Similarly, people adopt these " longitudinally " and " horizontal " terms commonly used to describe the orientation of some motion or some assembly, and this orientation is a benchmark with the axis of machine always, and direction is to determine with the direction that plate-like piece moves in this machine.At last, also want clear and definite, " upstream " and " downstream " term itself then is to be benchmark with the direction that plate-like piece moves in folding-labelling machine.

Now in conjunction with the accompanying drawings embodiments of the invention are done detailed explanation, so that the present invention is had better understanding, described embodiment is illustrative, but not determinate.These accompanying drawings are:

Fig. 1 a and Fig. 1 b show four critical parts forming apparatus of the present invention structure, are in control position simultaneously and shrink the shift position;

Fig. 5 is a block diagram, and the belt that shows middle conveyer when two side conveyers occupy minimum width shrinks the situation of displacement in this side conveyer belt;

Fig. 6 and Fig. 8 are for respectively along B-B among Fig. 2 b, the cutaway view of E-E line;

Fig. 7 is the top view of conveyer upstream extremity in the middle of the collapsible displacement.

Fig. 1 a and Fig. 1 b show the assembly of four critical parts of middle conveyer 1 structure that forms collapsible displacement.According to the arrow 2 of indication object moving direction in folding-labelling machine, Fig. 1 a shows and is positioned at device mass axis 3 downstream parts, and Fig. 1 b then shows and is positioned at device mass axis 3 upstream portion.Four critical parts constitute the primary clustering of this structure, longeron 4 on one is arranged in these parts, represent that with solid line it is in control position and represents that with long and short dash line it is in the position 200 of shrinking displacement simultaneously, so that can clearly show motion from a position to the another location.One side is being supported by a clip spare 5 longeron in the downstream on this, and the latter (sees that Fig. 2 a) is connecting laterally slip of do on the axle part 7 of folding-labelling machine two stands by a plain bearing 6; One side is being supported by another clip spare 8 in the upstream, and the latter slides on axle part 10 similar to the above by a plain bearing 9 (seeing Fig. 2 b).These two clip spares 5 are connected by longeron 11 once by locating dowel pin 12 and fix screw 13 (see figure 3)s with 8.Owing to be processed with two pairs of vertical slot 14 (seeing Fig. 1 a and 1b) on the face of clip spare 5 and 8, last longeron 4 can reduce along with an oblique motion (un mouvementfauchant) down.

Because the configuration of last longeron 4 meets the human engineering principle, so the actuating of this motion can manually be carried out, and because the cooperation of two damper elements 15, moving of these whole fat person's parts can be carried out easily, and each damper element is made of compressed-air controlled cylinder and piston.One end of these damper elements is connected with last longeron 4, and its other end is connected the end place in close longeron 11 two ends down.Axle part 16 about being screwed in the longeron is fixed damper element, and it is freely rotated.Therefore, longeron 4 forwards the contraction shift position 200 (seeing Fig. 1 a and Fig. 1 b) that a usefulness long and short dash line is represented with regard to the energy vertical shifting to from a control position on the list.

Fig. 2 a and Fig. 2 b are front view, show half of a half-sum upstream in the downstream of device 1, and demonstrate the position 200 into the occupied contractions displacement of last longeron 4.The bending stroke route 201 of conveyer 1 in the middle of when just on these identical figure, also showing described device on the one hand and be in the position of shrinking displacement with long and short dash line, also show two belts 101 and 111 on the other hand, medial axis 17 with respect to intermediate belt 30 is said (see figure 7), and they are respectively the belts and the belt (seeing Fig. 4 b) that is positioned at the side conveyer 110 of operator's opposite side that is positioned at the side conveyer 100 of operator's side.

Two screw rods 20 and 21 between the support of folding-labelling machine, can make device 1 make lateral register with its end portion supports between the support of folding-labelling machine.These screw rods pass the nut 22 and 23 by screw retention respectively, so that one is connected with clip spare 5, and another is connected (see figure 3) with clip spare 8.Install 1 integral body and driven on axle spare 7 and 10 by plain bearing 6 and 9 and slide, plain bearing is lubricated by oiling machine, and is connected with 8 with clip spare 5 respectively by screw 26 and (sees Fig. 4 a).

Fig. 5 expresses conveyer 1,100, three belt track routes of 110, and show the position that is in the contraction displacement when device 1, the position that each belt was got when mistake repeatedly was between two side conveyers 100 and 110.

Side conveyer belt 101 and 111 transmission are to realize by two belt pulleys 102 and 112 respectively.Because these two Transmissions are coaxial, they rely on mutually, and situation is not so just for the transmission of middle conveyer 1 belt 30 of collapsible displacement, and this conveyer is provided with a drive pulley 31 that is installed on the hexagonal axis spare 32 independently and (sees Fig. 2 a).Around a plurality of commutation rollers 33 and support roller 34 operations, each roller is connected with last longeron or following longeron by the screw rod 35 that passes its ball bearing of main shaft 36 (sees Fig. 4 a) to belt 30 in its stroke.Be added with somely to tensioning opinion 37 at the crooked stroke of each belt place, the latter can compensate belt issuable variation on length.Rotate the adjusting that set screw 38 just can realize belt tightening with hand, this set screw is placed in the opening 39 that processes on the corresponding conveyer side plate (sees Fig. 2 a).The effect of rotating set screw 38 is exactly that two tensioning opinions 37 move along opposite direction, thus individually tensioning or loosen each belt.

As clearly shown in Figure 6, it is converted into rectangular- shaped plate 40 and 41 and is fixed on the C.O.C or C.C face of longeron 4 by a plurality of screws 42 and 43 respectively with the upstream portion that the vertical sectional view mode has been showed the device 1 shown in Fig. 2 b.The effect of these plates is exactly a back-up belt 30, and avoids its curved hanging down that may occur, and this curved contraction displacement that can make middle device 1 of hanging down becomes inconvenient.

In folding-labelling machine of making, middle conveyer generally is lower than one and goes up the belt conveyer, so that be held in the operation of the cutting material between the conveyer belt up and down.For this reason, device 1 of the present invention can be provided with a crooked bracket of right angle type 50 up, and it can support any last conveyer commonly used.Fig. 2 b and 4a have showed with screw and the bracket of right angle type end have been fixed in situation on operator one side of clip spare 8.In order not hinder the perpendicular movement of longeron 4, vertically process two notches 52, so that make longeron motion around two screwings 51 in the clear.

Fig. 4 b is a cutaway view, shows intermediate transport device 1 position occupied between two side conveyers 100 and 110 commonly used.These side conveyers correspondingly include a longeron 103,113 respectively; One opening 104,114 can allow bracket of right angle type 50 pass through; With a plain bearing 105,115, be fixed on the corresponding conveyer longeron by screw 106 and 116 respectively.

As Fig. 7 in detail shown in, be provided with one and the roller 55 of axis 17 centerings at each end of last longeron 4.This roller is installed on the detouchable extension element 56, and the latter then is fixed on the concave surface of longeron 4 operator's sides with milled screw 57.

The contraction displacement of the device of realization the object of the invention is performed such, and at first two extension elements 56 that roller 55 is housed is taken off.To go up longeron 4 and be fastened on milled screw 60 on clip spare 5 and 8 and make on this longeron 4 (see figure 8) that gets loose by unscrewing two pairs then.Because the effect of damper element 15 is arranged, and last longeron can keep state of equilibrium, can not cause owing to unscrewing any danger that milled screw 60 produces.Impose vertical then in the above, last longeron will a first side reduce on opposite side ground then.Its perpendicular movement is to twist the axle part 61 and the bearing pin 62 that are inserted in the longeron 4 respectively by two to guide, and seamlessly slides in two pairs of notches 14 and (sees Fig. 2 a).Descend in case go up longeron 4, milled screw just can be tightened again, and the device 1 of whole collapsible displacement is owing to there is the effect of mobile screw (vis de chriotage) 20 and 21 to do shifted laterally along lateral shaft spare 7 and 10.The contraction of middle conveyer is shifted and has realized like this, and does not need to take off or get loose belt 30.In fact, the vertical shifting of last longeron is said the total length of drive belt 30 and is only produced minimum variation.Moved so the franchise of utilizing belt elasticity to bring just is enough to carry out this, and can not produce unacceptable stress, and there is no need to seek help from other any operational meanss.

Also can do some improvement within the spirit and scope of the present invention to the present invention.
